Cellular blue nevus tumor presenting as a submandibular lymph node in a 16-year-old

Area of Science:

• Dermatology
• Oncology
• Pediatric Pathology

Background:

• Cellular blue nevus is a rare variant of blue nevus, typically benign.
• Blue nevi commonly occur on extremities in adults, rarely in the head and neck region.

Observation:

• A rare case of cellular blue nevus presenting as a neck mass in a 16-year-old patient.
• The tumor invaded the submandibular lymph node and surrounding soft tissue.

Findings:

• This case represents an exceedingly rare presentation of cellular blue nevus in the pediatric neck.
• The tumor demonstrated invasion into adjacent lymph nodes and soft tissues.

Implications:

• Cellular blue nevus should be considered in the differential diagnosis of pediatric neck masses.
• Histological evaluation is crucial for assessing tumor aggressiveness and malignant potential in pediatric patients.
